To all whom it may concern:

Be it known that we, JAMES FRANK DUR- YEA and WILLIAM MERRIAM REMINGTON,citizens of the United States of America, residing at Springfield, inthe county of Hampden and State of Massachusetts, ave invented new anduseful Improvements in Internal-Combustion Engines, of which thefollowing is a specification.

This lnvention relates to internal combustion engines and es ecially tomeans to start amultiple cylin er engine having a jump spark ignitionsystem without crankmg the same; that is without being Obllged to rotatethe-crank-shaft one or more times to his ire or draw an-explosive chargeinto the cy iinders, the object of the invention being to rovide meanswhereby a quantity of com ustible may be introduced into the cylindersof the engine above the piston, there being, in an engine of the typereferred to, always one cylinder in which. the piston has passedover thecenter on the compression stroke, thus enabling the combustible in thatcylinder to be ignited by a movement of the switch to close the ignitioncircuit after retarding the spark.

This invention is particularly adapted to motors of the type specifiedas employed for propelling vehicles, and is thus illustrated in theaccompanying drawings, a portion of the dash of a vehicle being shown inconnection with the motor.

In the drawings forming part of this a plication,Figure 1 is a sideelevation of t ose parts of a multiple cylinder motor necessary to acomplete understanding of the invention which is shown applied theretoin its preferred form, certain of the parts being shown in dotted lines.a fuel reservoir showing a modification of the construction of theconduits running to the cylinders. Fig. 3 is a sectional elevation of avalve having a charge-measuring pocket or recess therein, the valve-plugbeing shown in two positions. partly in section, 0 the valve shown inFig. 3 thlsiview being taken at right angles to that shown in said lastnamed figure.

Fig. 2 is a side elevation of Fi 4 1s a side elevation,

Referring to these drawings, a, a,a indicate cylinder and the reservoir,as shown in Fig. 1, as this construction insures suflicient flexibilityin these connections to avoid breaka e or leaks which might otherwisearise from t e vibration of the cylinders, the reservoir usually beinsecured to some near by rigid support, as or instance to the dash d. Ifdesired, however, a single conduit 6 may extend from the reservoir (asshown in Fig. 2 t0 the farthermost cylinder, and be tapped at eachcylinder, as at f, for a short pipe g extendin therefrom to the clinder.

A vs ve h (the preferre form of which is shown in Figs. 3 and 4) isthreaded into the top of each cylinder, the pi es 0 being connected tothe inlet end of t ese valves by a flange coupling k, or otherwise.convenient formof valve to use for this purpxo e is an ordinary tapered1plug-valve, as s own, and to insure a tighttting plu a spring m may beapplied to it in the usua way to hold it to its seat in the valve-body.As shown in Fi s. 3 and 4 most clear] the valve-plug is milled off onone side t ereof to form a small pocket 1) between it and the body ofthe valve. On the plugis a crankarm g and when this is swung to theposition shown in dotted lines in these last named figures, thepocket 1) will be in communication with the passage 1' in the valve-bodywhich is a continuation of the pipe 0, and the pocket ma therefore fillwit the liquid fuel which wil flow into it from the reservoir. Extendthe valve-body, 11]. which the plug is seated down through the lower endof the body, are two sages s and t, the first of which communicates withthe ocket p when th plug is in the positions own insection in Fig. 3,the second passage, when the plug is .111 this position, registeringwith the venthdle o in the plug, -this hole in turn registering at itsouter end with a hole w in the wall of the valve-body. -An examinationof the dotted position of the plug will show that when in that positionthe inner ends of the two passages s and t will be sealed, thus cuttinoii all communication therethrou h with t e-cylinderfthe combustible int e pocket 17 being thereby protected against ignition. This is thenormal position of the valve'in each cylinder.

It will be noted that the crank-arms g are each-connected pivotally to arod 0:, the end The most from the tapered hole in p of which may extendthrough the dash within convenient reach of t e operator, there being ahook or the like on the end of it wherebyit may be moved endwise.Preferably the rod 2: is made in two parts, there bein a short length xthe ash and connected b a link y to t e end of the rod a: next to t 'edash, whereby there will be no binding efiect on that part extendingthrough the dash when as the arms g swing through the highest point of{heir arc the rod is raised bodily "more or ess.

As stated, the normal position of the parts is that shown in full linesin Fig. l, in which position each of the pockets 1) the plugs of thevalves on the cylinders 1s m commum cation through the i es c with thereservoir, the combustl h e flowing into the pockets, (see dotted'position in Fig. 3). When it is desired to start the -motor the operatorpulls the rod m to swing the crankarms to the position shown in dottedlines F ig; 1, and the contents of each of the w pockets flows into thecylinders, and as in multiple cylinder motors some one of the istons isalways in position ready for the ignition of the combustible, it is onlyneces sary to wait for a moment after havin 30 actuated the valves topermit the volatiliextending throu h" internal combustion motor, of areservoir for combustible, a pi e connection extending therefrom to a c[ihder of the motor, a valve in said pipe aving. a pocket or recesstoreceive the combustible, and means to actuate the valve whereby saidpocket or 45 recess ma placed, when the valvejs in one position, 1ncommunication with the reservoir and cut ofl from thecylinder, and inanother positionin communication with the cylinder and cut oil from thereservoir, there bein a vent passage in the valve adapted to lie placedin communication with the cylinder, when the pocket in the valve is alsoin communication therewith.
